GAS-EXHAUST REGULATOR.

SPECIFICATION forming part of Letters Patent No. 257,494, dated May 9, 1882.

Application filed November 21, 1881. (No model.)

To all whom it may concern:

Be it known that I, REUBEN K. HUNTOON, of Franklin, of the county ofNorfolk and State of Massachusetts, have invented a new and useful improvement in gas-exhaust regulators or apparatus for regulating the supply of steam to a steam-engine when used in operating machinery for exhausting gas from one or more retorts employed in the production of such gas; and I do hereby declare the same to be described in the following specification and represented in the accompanying drawings, of wh1eh- Figure 1 is a side view, and Fig. 2 a verti-' cal section, of an apparatus provided with my invention, the nature of which is defined in the claim hereinafter made.

In gas-exhaust regulators provided with a tank and a counterbalanced bell to work therein it has been found that owing to the mouth of the bell being entirely open the bell, under sudden variations in the pressure of the gas, was liable to move too far in the liquid, fhereby causing the engine to operate irreguarly.

The object of my present invention is the obviating of this ditficulty in a mannerand by means different from what has been heretofore employed. To accomplish such I place within the bell, and connect therewith by springs or an elastic connection, an inverted bell having one or more holes in its head, and adapted to slide vertically upon the gasinduct.

In the drawings, A denotes a conduit, which is to be supposed to lead gas from an exhaustpipe of one or more retorts and into the bell. This conduit extends upward within the tank B and the gasometer-bell (3, arranged therein as represented, the latter bell being suspended from a duplex sectoral lever, E, having a counterbalance-weight or series, F, of weights appended to it. The bell 0, open at its lower end, has within it an inverted bell, Gr, having one or more small holes, a, in its head I), such inverted bell being open at its upper end, and arranged concentrically with the main bell and the tank, and adapted to slide verticallyand freely on the conduit A. The auxiliary bell G rests upon a spider, H, that also slides freely on the conduit, and is connected with another such spider, I, fixed to the top of the main bell, the connections being rods 0 and a spring, at, to each. Each rod fastened to an arm of the lower spider slides freely in the arm of the upper one, and is connected with such. arm by the spiral spring (I, that encompasses the rod, the spring at its lower end being fastened to the rod and at its upper end to the upper spider. From this it will be seen that there is to the two bells an elastic connection, which, on a sudden rise of the main bell, will immediately thereafter gradually raise upward the auxiliary bell, as water in it may pass from it through the hole or holes a. The connectionrod for operating the throttle valve of the steam-induct of the steam-engine is shown at M, it being applied in the usual or a proper manner to the sectoral lever E.

From the above it will be seen that when the tank and the main and auxiliary bells are duly supplied with water, and the gas may increase in volume or pressure in the exhaust-main, the superior bell will be forced upward in the tank, and consequently the throttle-valve will be moved so as to increase the flow of steam to the engine-cylinder, and thereby cause the engine to work faster, an opposite result taking place as the pressure of the gas in the bell may diminish. The tendency of the main bell to rise too fast will, however, be checked or regulated by the auxiliary bell and the springconnections and the weight of the water in the auxiliary bell, the springs gradually lifting the auxiliary bell, and thereby causing water to flow out of it through the aperture (1.

What I claim, therefore, as my present improvement is- The inverted auxiliary bell and its elastic connection or connections,combined with the 90 main bell and the tank of the gas-exhaust regulator, and arranged and adapted substantiall y in manner and to operate therewith as set forth.
